There is only one class of drugs that lowers appetite outside of these GLP hormone drugs, those are stimulants like amphetamines. As someone on one of the GLP drugs for 3-4 months, and whose body tolerates it well, this is simply turning off the hunger switch. I will miss meals because I'm not hungry, since starting I have never felt "hangry" and I am satiated with small meals and do not feel hungry later. If I overeat, I will feel nauseous and sick.

I do not feel wired, foggy or feel like my personality or sleep cycle has been affected in the slightest.
